ABC News(REDDING, Calif.) — The woman who called 911 after finding missing California mom Sherri Papini said the 34-year-old looked terrified when she flagged down the passing driver from the side of the road.

Authorities are now hunting for the alleged kidnappers who Papini said dropped her off 150 miles from her home on Thanksgiving Day.

“I saw a woman with long blonde hair by the side of the road kind of frantically waving what looked like a shirt,” Alison Sutton told ABC News. “I figured if she was willing to risk being hit by a car, she must really need help.”

Sutton said she spotted Papini early in the morning of Nov. 24 and called police.

Papini, who had reportedly been held captive for three weeks, was able to flag down Sutton even though she was bound with restraints.

She told authorities her captors were two Hispanic woman armed with a handgun and driving a dark-colored SUV.

Investigators are now analyzing the restraints along with Papini’s clothing for DNA evidence as well as surveillance video in California’s Redding and Yellow counties.

The Shasta County sheriff told ABC News that Papini will be interviewed again this week.
